| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to CJ. Wor.{Arthur Wormald - General Works Manager} c. to Hs.{Lord Ernest Hives - Chair} EP.{G. Eric Platford - Chief Quality Engineer} X4083 E4/M24.10.22. GOSHAWK SPARKING SPANNER K.4083. We send herewith drawing No.LeC.1648 shewing the above. This spanner has been made so as to operate all six sparking plugs with reasonable facility. It is short enough to go underneath the Klaxon, and small enough we think to clear the ignition wire support, and owing to a number of tommy bar holes being rpovided we think it will be possible to conveniently handle it on No.1 plug. This drawing cancels the LeC. drawing shewing the spanner suitable for the sparking plug inclined at 40°. The body of the spanner has been knurled so that sparking plugs which have been loosened can be quickly undone. Will you kindly proceed to make, test and standard-ise this spanner.
